I have a Sony TRV16e, about 2 years old, and have lost original software. Sony assure me I don't need software to install this camera with XP but although it caputures the images fine, there is no audio (I can play back soundtracks, etc, but not the original sound recording). I have tried downloading the necessary software from Sony website, but my model isn't even listed! Before I spend 25 quid on the software from Sony, has anyone had the same problem happen, and how did you (if at all) resolve it. Thanks in anticipation.
